RF340T — 13.56 MHz transponder for SIMATIC RF300
The Siemens 6GT2800-4BB00 is an RF340T read/write transponder in the SIMATIC RF300 family, operating at 13.56 MHz with a 106 kbit/s transfer rate. It carries 8189 bytes of user memory on FRAM/EEPROM with an additional 4-byte UID and 20 bytes of one-time-programmable (OTP) memory. Block-by-block write protection on the OTP region prevents accidental overwrite of critical identification data after commissioning. Rated IP67/IPx9K, the housing withstands high-pressure washdown and temporary submersion — typical for food-and-beverage or pharmaceutical lines where the tag follows a product carrier through cleaning cycles. The PA12 material and silicon-free construction suit cleanroom-adjacent zones where outgassing or silicone contamination is a concern. Temperature range splits by operating state: -25 to +85 °C during read/write access, -40 to +85 °C outside the read/write area and during storage. That means the tag can survive a hot wash cycle (storage limit) but must be within the narrower band when the reader actually pulls data — a detail that matters if the tag sits on a pallet passing through a hot tunnel.
Mounting and integration
Fastened with two M3 screws through the 48 × 25 × 15 mm anthracite housing. No DIN-rail clip; the form factor is a flat tag meant for direct attachment to a workpiece carrier, pallet, or product holder. The 105 mm read range is reader-dependent — Siemens application note 67384964 covers the pairing matrix. Protocol is RF300-specific, not ISO 15693 or generic HF — it talks only to SIMATIC RF300 readers (RF310R, RF320R, RF350R). No cross-vendor compatibility; the tag expects the Siemens handshake.
Lifecycle and sourcing posture
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing confirmed at quote time. Minimum order quantity is 5 units per the description.
